Zoho Mail for WordPress

Zoho Mail Plugin helps you to configure your Zoho Mail account in your WordPress site, to send emails from your Site.

  • By using ’wp_mail’ function of WordPress, Zoho Mail plugin handles the custom send mail action anywhere from the entire site, without having to change/ configure in every occurrence.

  • You can configure your Zoho Mail account in your website to send email using Zoho Mail API.

Great plugin, but missing an important feature. We like to set it up to send from a noreply@ email address, but when the user or notification email are sent out, the "reply to" address is not used, rather the noreply@ email address. This is ineffective. If this feature is added, 5 stars… until then 3 stars.

Thanks a lot ! The plugin works OK! If it is for a wordpress "Contact form 7″:1- Install the "zoho mail" plugin, so that the Authorization Redirect URI is generated2- You must access api-console de zoho website.3- Choose the server option after entering and paste the "Authorization Redirect URI" that was generated in wordpress. With these data, the "Client Id" and the "Client Secret" that the plugin requests in the admin of the wordpress site are generated.

I spent almost one full day to find that reply-to custom header is not supported. So if you wish to set a different email to deliver the reply to, use the FluentSMTP instead of this one. Just saved you a couple of hours! Cheers!

I am a (satisfied) Zoho Mail customer and this plug-in sorted my SMTP problems from my Wordpress site in an easy and graceful manner. I had to apply the configuration twice, for some reason, but worked perfectly after that. Great work Zoho!

After installing and configuring the plugin it gave an error: Invalid Client Secret Someone posted a simple solution on the plugin forum. Just deactivate and then activate the plugin again. Problem solved. Works like a charm now. Developer please fix the invalid secret issue!
